The thread was left with things looking rosy regarding the installation of the Sony HU. However, it was not to be.
I, first of all, did what anyone else would and ordered an el cheapo fascia for less than £30. This unlike a few also has the correct step built into it so that the heater vent can fit correctly too unlike a few versions out there.

However, the ruler in that shot highlights a few issues that I'd contend with regarding fitting the HU into place.
Briefly they are down to:1) The lack of factory mounting points for a simple Plug & Play Double DIN installation
2) The low rent quality of a number of Double DIN fascias
3) Compromised usability of the Sony HU with the commonly available fascia adaptors.
The solutions are:1) Make/buy a cage to mount the HU into but it will also be compromised anyway due to the above
2) Get a left-handed fascia adaptor which will potentially work with a modified factory cage once a bit of trimming has taken place. The volume knob will still be compromised however
3) Get the Enfig fascia adaptor. This is the closest thing to a Double DIN Plug & Play kit with the Sony AX100 headunit. It also is a great quality kit and it shows.
For those seeking detail let's get into a mammoth long post. Stay awake at the back of the classroom now
1) From the factory, the Double DIN Sat Navs have a chassis/cage built into them so that they fit the car. As a result, you don't have a means to secure an aftermarket Double DIN bar the Chinese E46 Sat-Nav copies or the Eonon/Dynavin etc. This is a problem any Double-DIN user will have, irrespective of if they go with a shallow depth HU or heater cutting item.
This leaves you with a few choices
i) Make your own cage mounts up to secure the HU. This is possibly the cheapest option but it will get time-consuming, and add a chunk of hassle. One way this could be done is to butcher the factory Single DIN/Heater control panel cage. To get it to mount centrally will involve butching the thing a lot. It will also lose your means to go back to a factory installation in the future too short of buying another cage to fit into your car.
ii) Get a cage that bolts onto the factory bits take. The cage is also around £60 after delivery regardless of where you look. While it takes a chunk of fabrication out of the equation for something like the Alpine or Parrot shallow depth units it still potentially requires further fabrication.
incartec.co.uk/Pages/Product.aspx?P=37652)This fascia is not the best of quality and is primarily designed for HUs with button There is not much you can do about this but I'll come back to this point.
3)Because the Sony AX100 has a single DIN chassis that clears the heater box it introduces a new problem with the fascia which my previous photo alludes to. It can't sit flush with the fascia adaptor as its chassis rests on the heater box, removing any possibility of angling the HU to fit flush with the fascia. You're also left with a small gap between the HU and the bottom of the HU. You could file down to the recess towards the top of the fascia so that the HU sticks out slightly further. But then you'll always be left with another problem.
The volume knob will have no clearance on the left-hand side. Thus it will be tricky to adjust the volume with the HU unless you have steering wheel controls.
With this in mind, I started trialing other options. What were the choices?
Solutions:1) Offset the HU to one side.

IMO, with a left-hand fascia adaptor, this could work and you'd have room for the volume knob to work again. But the fascia kits aren't the best of quality still and depending on your preferences it does look strange with the HU stuck to one side of the aperture. Considering the look is part of the driving experience inside it's something you'll see all of the time. You can modify the factory Single DIN HU/heater panel cage a little to make this work and potentially do it cheaply. This is only my theory, however:
2) Get the Enfig kit specific to this headunit.
This is the most plug and play installation you'll get. Cheap however it isn't. I paid £80 to get the HU delivered to this country and Parcelforce robbed me for a further £24. Ouch! £12 of that was VAT and the rest was their 'handling fee'. Yeah, right.
This is a similar price to getting the fascia adaptor and Double DIN cage above. This fascia kit was almost a bargain if the heater relocation panel wasn't left-hand-drive specific. But it's time to install it. The first thing that struck me upon opening the kit was the quality of everything. It's something Enfig don't really show and the pictures don't do it justice. It has that rubberised coating feel and it all feels well made. It is a step up from other adaptors I have seen on the market for a long time. Not just the E46 but others in generall too.

On the bench the Double DIN cage is easy to assemble with the handed plates being an interference fit into the back of the main frame, requiring two screws to keep them in place.

Once everything is mounted onto the cage and the HU connected up the whole lot can be bolted into the car. Note the use of the factory screw locations.

All that is left to do is put the heater vents in on top of the Double DIN chassis as per the factory way and then screw/clip the fascia plate itself into position.

There is of course one catch left. The heater panel relocation. The part supplied by Enfig will not fit our cars due to it being a left-hand-drive part

What this means is Ms. Merkel had been meddling things for us long before Brexit! Basically, the heater panel curves differently. It' curves into a tighter line on the driver's side for each country. For people who drive on the right side of the road on the left (see what I did there?), it curves in tighter towards the bottom on the right. For people who drive on the wrong side it curves into the left. You can guess which side this panel curves into! But it is not the end of the world.
You can either buy this panel with an ashtray from BMW or without like the one above. You can also modify the original panel to accept the heater control unit (HCU) Basically you cut in two slots into the panel where the clips are on the bottom of the HCU. You will have a 3mm gap however between the HU and the switch panel once it is installed but it is one way to save cash here. Given how tired these panels get in E46s it is probably worth sourcing a new item.
And that is it! Besides mounting the microphone in a desired location like the steering column panel or on the windscreen the job is done! And doesn't it look good and give you much-improved usability? If you don't like Apple Maps Sony do sell a Sat-Nav module to plug into this HU for £180. It uses TomTom maps.
For the Android users this HU does also do Android Auto. I have yet to try that since my phone is obviously fruit based. I've got to get one of my 5-a-day y'no!
All in, this is another solution out there for people considering a Double DIN installation without a lot of fabrication and with a good chunk of flexibility regarding the head unit.
I did eventually surrender and go out to buy a BMW instrument panel so that the heater would sit correctly in its aperture.
And here they are side by side:
There, it looks fine, doesn't it?
Upon getting the right shot you can see the car's panel was quite scratched!
farm5.staticflickr.com/4695/25761621647_5a83cb216d.jpgWith that done it was time to install the new instrument panel and survey the magnificence. But would it be?
The answer is a very predictable yes! The car has become a lot more convenient and with a layer of technology a decade newer being brought into the car! It's served its purpose a few times!
In other places, people have asked me for a kit list for this setup. Here I will also give it seeing there are a few E46 owners about. The kit list includes:
-Enfig Fascia installation kit:
enfigcarstereo.com/ENFIG_RMK_E46_XAV1.html-Harness adaptor. Depending on your car and whether you want steering controls this can vary. I used the one for mine which is a Harman Kardon harness adaptor with steering controls:

-Heater relocation panel; You can use your existing part but there will be a 3mm gap between the heater control panels and the instrument panel. I went with a non-smoker panel from BMW
51167001409 - Non-Smoker Relocation Panel
The smoker item is over £100 with the only difference being it has a cigar lighter, and ashtray with it, all of which you can take from your item. Oh, and it has a light for the fag tray, which the non-smoker item doesn't.
You could go secondhand here, but almost all of them are tatty and they go for £40-50 which seems crazy for a tired item.
You'd have thought after splashing the cash here I'd stop. Well, this is me, and this is RR. I'm sure this car has given me a disease of sorts. Maybe it was the car before that, or the one before that one, or before...
